The advantage to putting this bench together with dovetails, mortise and tenon, splines AND "all thread" is that it leaves you options as you go. You can put the thing together, look at it and, if you want to add something or change something you just disassemble and make the change(s).
In this case, because the front apron is a smidge over 2 inches thick I could router 3/4" deep "square" dogholes in the inside face and still have some meat left on the apron. A template, router bit and template guide and a boatload of chips later - SQUARE dogholes. Of course, after the glue had dried on the template and I'd done a bunch of test cuts on scrap to get the depth right - THEN I discocvered that my template "faced the wrong way". The angle on the holes would be AWAY from the vise jaw rather than leaning towards it. OOPS!
Cutting the dogholes went well - on the apron. Now I have to figure out how to do the opposite leaning doghole in the end vise outer jaw.
Anyway - here's yesterday's dust making. (all one line)
